Heat dissipation structure for light bulb assembly

Abstract

A heat dissipation structure for a light bulb assembly includes a holder, a heat dissipating cover, and a light seat. The holder includes a socket and a receiving space defined in the socket to receive a circuit board, the socket includes a first abutting portion formed on a peripheral side thereof and at least one first coupling portion arranged on a lateral side thereof. The heat dissipating cover includes a through hole for inserting the socket, and at least one cooling fin arranged around an outer peripheral side thereof. The light seat is used for installing a LED light, which includes a second coupling portion connected with the at least one first coupling portion, and a second abutting portion retaining the heat dissipating cover with the first abutting portion.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a heat dissipation structure for a bulb, and more particularly to a heat dissipation structure for a light bulb assembly which is capable of assembling the light bulb tightly without using screws.BACKGROUND OF THE INVENTION[0002]A conventional bulb emits light by ways of tungsten wires, so it has a simple structure and is replaced easily. An incandescent light bulb contains a spherical lampshade and a connector disposed on a distal end of the lampshade, the connector has threads to screw with a holder. When transmitting a power source, the tungsten wires in the lampshade emit heat and light, and the light penetrates the lampshade to make an illumination. However, during an operation of the incandescent light bulb, a lot of heat will generate, thus having a great power and energy consumption and a short service life.[0003]A light emitting diode (LED) is a solid light source used to transform electricity energy into light en...

AI Technical Summary

Benefits of technology

The solution enables secure connection of all components without screw holes, simplifying the manufacturing process and preventing cracks, while effectively dissipating heat through cooling fins and an aluminum plate for improved thermal management.

Problems solved by technology

However, during an operation of the incandescent light bulb, a lot of heat will generate, thus having a great power and energy consumption and a short service life.

Nevertheless, if the light emitting diode (LED) has more power and larger brightness or its module generates larger heat, its heat is difficult to dissipate.

Therefore, the heat dissipation is a technological bottleneck for the light emitting diode (LED).

But such a light emitting diode (LED) has a large size that will occupy space.

Besides, a crack of the housing will occur because of an improper force during the screws are inserted to the screw holes.
